Serial No. 221,143.

The present invention relates to a method of transferring dyestuHs and more particul'arly to a method of transferring water soluble dyes to porous or absorbent materials such as fabrics, biscuit ware, unglazed earthen ware, walls and the like.

Objects and advantages of the invention Vwill be set forth in part hereinafter and in part Will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by means .of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel steps, method, combinations and other improvements herein shown and. described.

rIhe present invention has for its object the provision of a novel method of ornamenting porous or absorbent surfaces by transfer ring designs in soluble dye thereto, and more particularly to a method of transfer ornamentation which produces strong transfers, even om surfaces having a relatively low porosity, -while avoiding the bleeding of the dyestuif on the absorbent or porous surface.-

A further object of the present invention is the provision of a' method of transfer decora- `tion which can lbe carried out-rapidly and economically. The invention also provides a method for the transfer decoration of Silks, satins and other textile material with soluble dyes in such a manner that no water marks or spotte'dedges are formed on the material as a result of carrying out of the method. The invention also provides a method of ornamentation Which permits the elimination of the dusting step in themanufacture ofl the transfers.

In accordance with the present preferred and -illustrative manner of carrying out the present invention a transfer, comprising a sheet of paper or the like bearing 'a design thereon in soluble dve is pressed Vagainst the surface to be-decorated which is moistand has been coated with a non-bleeding agent, such as a mucilaginous gum, thereby causing the dye to be transferred fromv the transfer to the surface to bedecorated. The muoilaginous gum not only prevents bleeding of the dye, thereby preventing blurring of the lis adhesively maintained in place and the transfer operation is effected without further attention.

While the method of the present invention is preferably carried out with transfers in which a water-soluble dyestuif is imprinted on a temporary support such as paper, it is also applicable to other types of transfers such as that shown 1n my prior Pa'tent, No.

The present invention iindsa large field of usefulness in connection with the decoration of tile walls which may afterwards be provided with a protective coating of clear lac- -quer or other transparent material;

0f the drawings:

Fig. 1 is a diagrammatic plan view of a design transferred accordingto the invention, certain parts being broken away to show the elements of the ornamentation; and

Fig. 2 is an enlarged vertical cross-section taken on line 2-2 of Fig. 1.

'Referring now din detail to the present preferred and illustrated 'manner of carrying out the method of the invention, the transfers employed are preferably formed by printing the desired ornamental design in one or more colors on a temporary support,

such as paper, 'using an ink containing awater-solnble dve. rated. which is preferably porous or absorbent, is preliminarilv coated with alaver of a gel formed by dissolving powdered gum tragacanth or gum karaya. with or without a preservative such as benzoate of soda. which has been thoroughly mixed with and swelled bv water to form a mucilaginous liquid. While the mucilaginous coating on the surface to be marked or ornamented is moist, the transfer sheet, printed with the design in water soluble dve, is placed on the surface and pressed into firm and even contact therewith, where it is allowed to remain undisturbed for a short period of time and while the dye is transferred from the paper The surface to be deco-A Sil transfer base to the porous or absorbent surface, while bleeding of the soluble dye is prevented by the lm of mucilaginous material Which separates the transfer. 'trom the surface to be decorated.

Referring1 now to the embodiment of the invention illustrated by way of example in the accompanying drawings, the Various instrumentalities employed in carrying out the novel method of the invention are shown in their assembled relation, and the components of the completed ornamentation are indicated by printed legends. It will be understood that the base shown in the drawings may be any porous surface, such as wallboard, tile, silk, satin or other textile material. The non-bleeding' agent is indicated as mucilage in the drawings, but it will be understood that the broad principles of the invention are equally adapted to the use of any substance in this relation which will provide a suitable non-bleeding agent for the transfer of the soluble dye-stuffs to the porous base. i layer of lacquer or other transparent hn is indicated as covering' the transfered design, but it will be understood that the invention is in no sense limited to the use of such .f1-protective film.

The invention in its broader aspects is not limited to the specific steps and ingredients shown and described but departures may be made therefrom within the scope of the accompanyinaciaims without departing from the principles of the invention and without sacritcing its chiei2 advantages.

Claims? l. A method of transferring soluble dves om a carrier to an absorbent surface comprising coating the surface with a solvent thickened with a mucilaeinous a'um and immediatelv contacting the dyebearina face of the carrier with the coated surface to cause the dye to be transferred to and vabsorbed by the surface.

2. rlfhe method of transferringn designs or markings to an absorbent surface which comprises preliminarily applying a laver of moistened mucilaginons material to the absorbent surface, and thereafter contacting a surface bearing a design in water-soluble dve with the surface to be marked whereby the dye is transferred to the surface to be marked without bleeding or distortion.

3. The method of transferring` designs or markings to, an absorbent surface which comprises forming a mucilag'inous colloidal j el by mixing water and a powdered gum, applyina said jel to the absorbent surface, and thereafter contacting the design-bearing surface of a transfer sheet having a design in soluble dye with the coated absorbent surface to be marked.

4. The method of transferring designs or markings to an absorbent surface which comprises preliminarily coating the surface with a mucila ous substance, thereafter placing the deldign-bearing surface of a. trans fer sheet in contact with the coated surface to be marked, whereby the design is transferred to the absorbent coated surface, drying the decorated surface and applying thereto a protective transparent coating et lacquer or the like.

rllie method oi traneterriner designs which comprises coatinga porous surface with a non-bleeding agent, and placing the design-bearing surface of a transf i sheet having a soluble-dye design thereon into contact with the coated surface in the presence of a solvent for said dye.

G. The method of transferring designs which comprises coating a porous surface with a non-bleedinv agent, and placing the design-bearing surface of a transfer sheet having a water-soluble-dye design into contact with the coated surface iro the presence of water.
